Hi! Need a couple of tips.
Didn't quite follow the guide in one particular area - Lando farming. Since I've had him from chromium (Wedge didn't come despite innumerable rerolls) I thought it would be nice to have some additional gun power. So I farmed 4* GS while waited for new arena, accumulating energy and spending cantina energy only, then farmed Lando to 6*, then came up 10 GS shards from challenge and I decided to add 55 more to make him 5*. And now came lvl50 and all that mods battles & challenges.
The question is: should I farm Lando's 100 shards asap or should I farm and invest in some 3* (or maybe 4*, haven't tried tier2 challenge yet; btw can it be done ov lvl50, gear 6/7?) for arena team?
Offtop: you described GW "ridiculously easy" until lvl80+; it is not if you don't have Wedge from the start. In my case it is hard as hell from lvl45. Didn't finish 3 times already and stuck with another one right now. The problems are: 1. "Arena team vs GW team", guess who have advantage when your TM and/or cooldowns are not in optimal shape; 2. protection: your toons lost it long time ago and opponents have it full and fresh. On the other hand I finish top-3 in arena from day 1, and all credits go to you and your guide.
P.S. As I mentioned earlier, haven't seen Rex in Guild store a single time yet. And I checked every single shipment update. So "Pre-Level 60" farming Rex might be impossible since he is not available before lvl60.
